As a kind of complete orthogonal polynomial system, U system has many good properties such as orthogonality and convergence.

作为一种可选定次数的完备正交多项式系统，U系统所定义的矩具有标准正交性、收敛性等优良性质。

The thesis also draw several conclusions as follows:(1) Orthogonal experiment design method can be viewed as a special case of genetic algorithm, i. e. a genetic algorithm with a fixed initial population, an oriented-mutation operator and one evolution epoch.(2) In terms of running steps, genetic algorithm is more complex than orthogonal experiment design method.

论文首次对正交试验设计法和遗传算法这两种独立发展起来的方法进行比较研究，提出(1)正交试验设计法是遗传算法的一种特例，即是一种初始种群固定的、只使用定向变异算子的、只进化一代的遗传算法；(2)遗传算法产生的优化解优于正交试验设计法产生的优化解，且遗传算法处理交互作用项的效率高于正交试验设计法；(3)遗传算法的步骤比正交试验设计法复杂，所需的试验次数也要多。

The effect of process parameters such as complex temperature,quantity of urea,stirring rotation rate,reaction time,washing times and the quantity of washing agent on product quality and yield is studied, the suitable production conditions are gained.

Furthermore, it expanded the scope of it s application, drew up fractal graph w it h more higher number times end more complex root value, added the thought of escape time.

在此基础上加入逃逸时间算法的思想，绘制出了次数更高、根值更加复杂的分形图形，进一步扩展了它的使用范围。

They will cover a variety of topics, for example, computability and relative computability results for different k inds of objects and services, in the presence of various numbers of failures.

它将包括不同的主题。例如，可运算度和针对不同物件及服务相关联的可运算度结果，在不同次数之失败当中的呈现。

An algorithm of error analysis is proposed to avoid the conflict between the precision and the computational burden. The quantitative error of the reliability indices can be given through the error analysis.

论文提出了可靠性评估误差分析的实用算法，为解决蒙特卡洛模拟法精度和抽样次数的矛盾提供了有效的解决途径，为可靠性指标提供了量化误差分析。

The simulation results prove that the proposed algorithm can cut down the complexity distinctly, even to more than 20% at low SNR and high condition number.

On defining the conditional threshold of discretized density evolution, a method for designing the time-invariant quantized decoder with finite levels, which can approach the optimal time-varying one and hence the continuous decoding, is proposed.

应用Shannon率失真理论以及密度进化理论，阐述了最佳量化译码的时变特性，建立了离散密度进化的条件阈值概念，提出了二元输入对称信道上逼近最佳时变量化译码、进而接近连续译码的时不变量化译码设计方法，推导了量化和积算法与最小和算法的等价条件，从误码率性能、错误平层和平均迭代次数等三个指标全面衡量量化译码性能； 5。

That means that if you intend to repeat an experiment until the first success, then, given that the first success has not yet occurred, the conditional probability distribution of the number of additional trials does not depend on how many failures have been observed.

无论之前试验了多少次，都不会影响下一次出现成功所需要的次数。不知道为什么，看到memoryless这个词，觉得有一种全新的感受。曾经跌倒，又有什么关系呢小王子说，你知道，路还长，我带不动自己的身体，因为太重了。。。身体的沉重，有很大部分是因为回忆。

Oil some orders are to pay attention to driving the behavior to dawdle that the result of study reveals the limousine driver: Open the car light, driving a vehicle steadily of more than 100 kilometres per hour, driving a vehicle steadily of 50 to 70 kilometers of speeds per hour, it make air conditioning, engine last number of times, take number of people, speeds idle, wet, cloudy day, 70 to 90 kilometer is the urgent to drive a vehicle, pass through go up a slope by highway section,etc.
